sensor. It is important to avoid using any caustic chemicals on the touch sensor. Do not use any vinegar-based
solutions.
Apply the cleaner with a soft, lint-free cloth. Avoid using gritty cloths. Always dampen the cloth and then
clean the sensor. Be sure to spray the cleaning liquid onto the cloth, not the sensor, so that drips do not seep
inside the display or stain the bezel.
MSR maintenance
To clean the MSR (magnetic stripe reader), swipe a standard cleaning card through the MSR a couple of times.
You can order a standard cleaning card online. You can also put a thin oil-free cloth around a credit card.
Cleaning the printer
Because of the way the printer sits while in use, it is likely there is a buildup of paper and other debris from
the knife. HP recommends that you keep the printer in working order by periodically cleaning the debris from
the printer.
To clean the printer, open the cover, remove the paper roll, and then use a can of compressed air to blow the
debris out from the bottom plate where it accumulates.
Cleaning I/O ports
The mobility system has a series of ports. Dust and debris can collect in these ports, which can reduce
connectivity and performance. Use a battery-powered vacuum to remove any debris that has accumulated in
and around these ports.
Updating drivers and firmware
HP recommends that you regularly download and install the latest drivers and firmware updates to help
enhance system performance, resolve known issues, and avoid replacing parts unnecessarily.
Go to
to download and install the latest drivers and BIOS updates for your
specific Retail Point of Sale model.
